How electric currents are formed in the human body

Fenghe Zhongshu Sheren Jia to the early dynasty Daming Palace (Cen Shen).

The way of current passing through the human body: the current that passes from the left hand to the right foot, the heart passes the most current.

Because the heart is on the left, under normal circumstances, most of the current flowing through the left hand to the feet will flow through the heart, and this route is the most harmful to the human body, that is, the shortest route that flows through the heart, and the most harmful, such as the hands at both ends of the fire zero line. The path of electric current through the human body, from the outside, the electric shock from the left hand to the foot is the most dangerous.

Legs and Legs Legs and Hands Hands and Hands.

Where in the human body is electrocuted, that is the way the current flows through the human body.

The electric current in the human body is generated by electric shock or is accompanied by very weak current and potential changes by the neural activity and muscle movement of the organism, which is called biological current, such as ** current and cardiac current.

The safety voltage is not higher than 36V, the continuous contact safety voltage is 24V, the safe response current is 10mA, and the degree of harm to the human body is mainly determined by the size of the current through the human body and the length of the energizing time. The greater the current intensity, the greater the fatal danger; The longer it lasts, the more likely it is to die.

The minimum value of current that can be perceived by a person is called the perceived current, which is 1 mA for AC and 5 mA for DC; The maximum current that a person can get rid of after an electric shock is called getting rid of the current, which is 10mA for AC and 50mA for DC; An electric current that is life-threatening for a shorter period of time is called a lethal current, and a lethal current is 50mA. In the case of protection against electric shock, the current allowed by the human body is generally 30mA.

Hello, it is a pleasure to serve you and give you the following answer: the current bye through the inside of the human body means that the current passes through the human body from the outside, through the tissues and organs inside the human body, and finally reaches the outside of the human body. This condition can lead to serious injury and even death.

The steps to solve this problem are as follows:1First of all, make sure that the power supply has been disconnected to prevent the current from continuing to flow through the body.

If the injured person has significant burns, they should be moved to the hospital immediately for acceptance**. 4.If the injured person has no visible burns, the person's heartbeat and breathing should be checked immediately, and if the heartbeat and breathing booth are stopped, CPR should be performed immediately.

5.If the injured person has no visible burns, but has obvious symptoms, they should be taken to the hospital immediately for acceptance**. Personal Tips:

1.In any case, it is advisable to avoid the passage of electric current through the human body to avoid accidents. 2.

If a situation occurs where an electric current passes through the body, measures should be taken as soon as possible to prevent the injured person from getting further harm. 3.If the injured person has significant burns, they should be taken to the hospital immediately for the chain change**.

4.If the injured person does not have significant burns, but has obvious symptoms, they should also be taken to the hospital immediately for acceptance**.

The electric current is called the current intensity of the electric current that passes through any cross-section of the conductor per unit time, and is formed by the movement of electric charges.

Electric currents are formed by the movement of electric charges, and currents are formed when the free electrons in a conductor move directionally under the action of an electric field. The free turbulent electrons have a high degree of freedom of movement in the conductor, and under the action of the applied electric field, they are driven by the electric field force and move along the direction of the electric field. Since the free electrons have a negative charge, the direction of the current formed while moving is opposite to the direction of the electric field.

The positive charge in the conductor also moves, but it is negligible due to the less positive charge and the smaller contribution to the current. Inside the conductor, electrons are shared and can move freely back and forth in the metal lattice that the conductor is made of. When there is an applied power supply that connects the positive and negative electrodes to both ends of the conductor, an electric field is generated inside the conductor.

Under the action of the electric field, the electrons are driven to move from the negative electrode to the positive electrode.

When an electron moves, the electron that leaves its original position leaves a positive charge ionic vacancy, which is equivalent to the movement of a positive charge, but because there is less positive charge, the contribution to the overall current is relatively small, and the current is mainly formed by the movement of the negative charge, while the positive charge rarely moves. In conductors, electrons are affected by the electric field force, and the speed of movement is proportional to the electric field strength, which is also hindered by the resistance of the conductor and the collision factors.

The formation of electric current is a fundamental concept in the field of electricity

1. Conductor is the key factor in the formation of electric current. A conductor is a substance with good electrical conductivity, and the free electrons in the substance are able to move freely under the drive of an electric field to form an electric current. Parameters such as current characteristics and conductivity may vary from conductor to conductor, which also affects the magnitude and nature of the current.

2. According to Ohm's law, there is a dense liquid cut-off relationship between the current and voltage and resistance in the circuit. Resistance is an obstacle to the current current, and in the conductor through the resistance, the electrons will experience more collision and resistance, slowing down their movement. Voltage, on the other hand, is the driving force for the formation of electric current, and the magnitude of the voltage determines the strength of the electric field, thus affecting the magnitude of the current.
